在ios中创建异步串行队列

Question

我需要创建一个异步执行的队列，但任务执行的顺序必须是串行的

dispatch_queue_t queue;
queue = dispatch_queue_create("com.test.app", NULL); //create a serial queue can either be null or DISPATCH_QUEUE_SERIAL

dispatch_async(queue,
                ^{

                //Mycode for doing background http

                }

Answer 1

我认为你正确地做到了，

dispatch_queue_t queue;
queue = dispatch_queue_create("com.test.app", NULL); //create a serial queue can either be null or DISPATCH_QUEUE_SERIAL

dispatch_async(queue,
                ^{
task1;
task2;
...

all this tasks wil be done done sequentially 


                }
